Question

the fact that older locusts use less energy to fly than younger locusts suggests that a. younger locusts are incapable of flying efficiently b. efficient flying is an innate behavior that is only apparent in some locusts c. the older locusts have learned a more efficient way to fly d. flying is a learned behavior that the younger locusts must practice please select the best answer from the choices provided a b c d

Explanation:

Since older locusts use less energy to fly, it's likely they've learned a better - flying method. Option A is too extreme as younger locusts aren't necessarily incapable of efficient flying. Option B is incorrect as the info doesn't suggest efficient flying is innate and only in some locusts. Option D is wrong because the focus is on the older locusts' efficiency, not that flying is learned for younger ones to practice in general.

Answer:

C. the older locusts have learned a more efficient way to fly
